Thanks for that explanation. I'd never heard of a white elephant before.
No problem. One of the major delimmas facing the American military today is identifying projects that are actually white elephants. Do we really need a few hundred Raptors for the airforce, when other planes are good enough for air superiority, and drones make better bombers?
Heck, drones are one of those inventions that make a lot of other things white elephants. Drones have made white elephants out of a lot of manned planes and fighter bombers, simply because drones are much cheaper and still able to deliver precision strikes in an insurgency environment.
I'm really just playing devil's advocate here, but if one of these guns can take out a reaper, and so can a fleet, then surely the only question is whether the gun "costs" more than a fleet? I put "costs" in inverted commas because there's not just material considerations; for example I imagine that training the crew of an entire fleet takes a lot longer than training the crew of one gun, and there's the cost in lives when the fleet gets wiped out as well.
This is where distributed risk, partial costs, and versatility comes in.
In military terms, it's a Bad Idea when all your assets are at one point that can be ruined. And in engineering terms, it's a Very Bad Idea when an entire system rests upon one component.
A fleet represents a distributed investment. More or less, each indivual part of the fleet can afford to be lost. If you lose have a canon, you have exactly 0% utility of a canon. If you lose have a fleet, you at least have half the strength to still work with. This is not only vital in defense (what if the Reapers launch the first strikes on our canons?), but also in the offense: losses are unavoidable, but distributing them across replacable parts helps with reconsolidation and advance. If two Klendagon Canons both lose half their structure, you have two dud canons. If you lose half of two fleets, you can consolidate them back into a fleet.
Fleets also represent distributed
risk. The chance of something, anything, going wrong and ruining a whole fleet is far less than destroyign a single ship. The eggs-in-one-basket risk, if you will. The Reapers only have to get a first-strike on one ship, or indoctrinate one set of crew, to ruin the Klendagon canon. The Reapers have to do a lot more to a lot more targets to get anywhere close to the result on a fleet. This goes back to the first part of a distributed investment as well. Imagine you were fighting Klendagon canons, for example: would you want to face them with a smaller number of Klendagon canons, where every enemy hit means a loss of a fleet? Or would you face them with a fleet, where the Klendagon canon can only take out a fraction of your forces in each strike? Now replace 'Klendagon canon' with 'Sovereign-type dreadnaught.'
Versatility and utility is the real thing. Even if we're really generous with the Klendagon canon surrogate (one Reaper-killing shot every minute), how useful is that against, well, anything other than Reaper dreadnaughts?
Even if you establish that a fleet and a Klendagon canon have the same effectiveness against Reaper dreadnaughts (which we dispute above, but concede for this particular example), an over-powered weapon can suffer from too-big-to-use. It's not really warranted to use against Reaper cruisers or frigates: they'll just eat up you guns, and then in the next minutes the Reaper dreadnaughts will be called or they'll blitz your Klendagons. A galactic-scale weapon isn't exactly fit for sniping fighters out of the sky. You can't use it for tactical orbital bombarment, because you won't have a planet after you fire it a few times... and you'll kill the friendlies in the area. A single cannon-carrying ship isn't going to have the logistical lift to pick up and carry lots of supplies and resources to win ground battles either.
And, most of all, a Klendagon canon can only be at one place at a time, unable to do those 'small' things. A fleet can break up and do a lot of small things in a lot of different places at the same time.
